Specification of Letters Patent.

Patented Sept. 21,, 1915.

Application filed May 26, 1915. Serial No. 30,597.

provide a device of this character which consists essentially in a two-part wedge adapted to be engaged at its pointed end between the bottom of the door and the door sill, and a floor engaging member, by means of which the wedge is held against movement away from the door sill, whereby any attempt to open the door will, when the device is properly positioned, have no effect other than to more tightly wedge the lock between the door and sill.

A further object is to provide a locking device of the character described in which the two pieces of the wedge lock are longitudinally adjustable with respect to each other and are accompanied by set screws or equivalent securing means, so that the two pieces may be adjusted to vary the taper of their pointed terminal to accommodate the device to different doors.

Another object of the invention is to provide a door checking device of the character specified which is simple in construction and may, therefore, be cheaply manufactured and is capable of ready application to or removal from the door.

The above, and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are described in the following specification, and then more particularly pointed out in the claims which are appended hereto and form part of this application.

With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a perspective view of the device showing the two pieces of the block disassembled, but indicating the manner in which they are adapted to be connected to form an operative wedge block; Fig. 2 is a side elevation of the wedge block showing the same applied to a door and door sill, these members together with the floor being shown in section.

The checking device of the present invention includes a block A formed from two adjustably connected sections 10 and 11, a set screw 12, and a floor engaging member 13.

The floor section 10 of the block A is preferably formed as is the upper section, from a block of hard wood and is beveled upwardly on its lower face and at the forward end thereof, as indicated at 14. The upper face of the section 11 is also beveled at the forward end of the section to form a forwardly and downwardly inclined wedge face 18. The wedge faces 14 and 18 are thus, as shown best in Fig. 2, adapted to define a wedge point B. As a'means for securing the two sections of the block in longitudinal adjusted relation to each other, I employ the set screw heretofore designated by the numeral 12. This member is preferably provided with a wing head 15 and is threaded at its lower end into a receiving bore 16 formed in the section 10. A set screw is disposed within a longitudinal slot 17 formed in the upper section. It will now be apparent, particularly upon reference to Fig. 2, that when the two sections of the block are assembled, they may be longitudinally adjusted one over the other, to cause the tapering faces 14 and 18 to wedge against the sill and door, respectively and then be secured in adjusted position by means of the set screw. I

As a means for holding the block against sliding movement over the floor, after the wedge point B has been'inserted between the lower edge of the door and the door sill, I provide a substantially T-shaped floor engaging member, the bight portion of which extends through a transverse bore 20 formed in the upper section 11 adjacent the rear end thereof. The arms of the U-shaped fastening member pass down across the side faces of the block and project beyond the lower face of the section 10. The terminals of the arms of the U-shaped fastening member are, of course, sharply pointed so that they may be readily urged into the floor.

As best shown in Fig. 2, the U-shaped fastening member serves to hold the block A against movement away from the door sill, when the ends of the floor engaging member have been properly engaged with the floor.

Obviously, therefore, any attempt to open the door will cause the door to ride over the inclined wedge face 18, which since it inclines upwardly and rearwardly, will prevent the door from being opened.

In reduction to practice, it has been found that the form of this invention illustrated in the drawings and referred to in the above description as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that various minor changes in the details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of this invention, as defined by the appended 7 claims.

In case the space between the bottom edge of the door and floor is unusually small, the upper section of the block may be employed alone, hence it carries the holding member 13 and may, therefore, be held against movement on the floor.

What is claimed is 1. A door check including a lower block section, an upper block section mounted for longitudinal adjustment upon the lower block section, means for holding the block sections in adjusted relation, and a floor engaging member for holding the check against movement with respect to the sill of the door.

2. A door check including a lower block section, an upper block section, said sections being adapted for longitudinal adjustment with respect to each other, means for holding the block sections in adjusted relation, and a floor engaging member carried by one of the sections for holding the block against movement away from the sill of the door.

3. A door check including a lower block section, an upper block section, said sections being adapted for longitudinal adjustment with respect to each other, the forward end of each section being beveled to provide a wedge face, whereby one end of the block is wedge shaped and is adapted to be inserted between a door and a sill, said upper section being provided with a longitudinal slot, a set screw passing through the slot and into engagement with the lower block section, the head of the screw being engageable with the upper section for holding the two sections in longitudinal adjusted position, and a floor engaging member carried by one of the sections for holding the block against movement away from the sill.

4. A door check including a block consisting of an upper block section and a lower block section, means for securing the sections in longitudinal adjusted relation to each other, the forward end of each section being tapered, whereby the forward end of the block constitutes a wedge adapted to be inserted between a door and sill, and a substantially U-shaped floor engaging member having its bight portion extending transversely through one of the block sections.

and having the terminals of its arms pointed for engagement with the floor, whereby the block is held against movement away from the sill. i

5. A door check including a wedge-shaped block member, adapted to be engaged between the door and the sill thereof, and a substantially U-shaped floor engaging memher having its bight portion extending transversely through the block and having the terminals of its arms pointed for engagement with the floor, whereby the block is held against movement away from the sill. In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
